Believe it or not, I've got a really bad metabolism. One burger and I'm done. I'm not a guy that puts away 10 burgers.
I could never gain much weight. I've always had a fast metabolism.
I have a lot of adrenaline. I have a naturally fast system. But I love to eat, and I am not skinny.
Luckily, I have a fast metabolism.
I have an enormous metabolism, so I'm lucky.
I put on weight easily and lose it equally fast.
I think I must have a super-fast metabolism.
I'm lucky: I've got one of those fast metabolisms where I can eat whatever I want, and I don't put on weight. But I know that's only when you're young. It'll probably hit me when I'm 30.
I like carbs and I like junk food, and I don't gain any weight from them, so I've been slightly abusive of my body because of this.
I have an incredibly high metabolism.
I hate to say this, but I'm one of those people with an extremely fast metabolism. I eat, eat, eat, and yet I can't seem to gain any weight.
I'm a late developer in everything. I have a fast mind and fast metabolism, and I'm an intense worker, but in terms of life development, I'm way behind.
I can gain 20 pounds in a heartbeat.
